LOAD RATING CHART E-1 TRANSPORTABILITY INSTRUCTIONS F-1 10,000 LB CAPACITY ALPHABETICAL INDEX Index-1 HEADQUARTERS, DEPARTMENT OF THE ARMY MAY 1998 TM 10-3930-673-10 WARNING • DO NOT STOP QUICKLY. It is possible to drop a load which could result in load damage, or injury or death to personnel. • Do not downshift at high speeds. Vehicle will slow suddenly which could result in load damage, or injury or death to personnel. • Do not turn fast. This may cause forklift to tip, lose the load, and possibly cause injury or death to personnel. This is particularly true in the four wheel steering mode. Turn vehicle in a lower gear or a slower speed. WARNING • Do not travel with the automatic fork level switch in the ON position. It is possible to drop a load which could result in load damage, or injury or death to personnel. • Use care when backing up. Have someone direct you if you cannot see where you are going. Watch clearances. Failure to do so can result in load damage, or injury or death to personnel. • Do not operate vehicle with the emergency steer switch in the OFF position. If engine power is lost, there will also be a loss of emergency steering capability. Failure to follow this precaution could result in injury or death to personnel. WARNING • Use care when handling and transporting ammunition pallets. Failure to do so could result in injury or death to personnel. • Never move any part of vehicle or load near a power line or overhead wires. Failure to follow this precaution could result in immediate injury or death to personnel. • Ensure that counterweights are in place. An unbalanced vehicle could tip over and could cause injury or death to personnel. • Always lift load from its resting spot before extending or retracting the boom. Always extend or retract the boom before lowering load to its resting spot. Failure to do so could cause vehicle instability and result in injury or death to personnel. Refer to Appendix E for Load Rating Chart. • Do not lift more than one pallet with forks. Pallets may topple and result in load or vehicle danger or injury or death to personnel. • Always retract the boom before lowering or transporting a load. Failure to do so could cause vehicle instability and result in injury or death to personnel. a TM 10-3930-673-10 WARNING • Do not exceed 45% grade (25°) longitudinally. Vehicle becomes unstable as fluid levels are shifted. Internal components may not be properly lubricated causing vehicle damage. Tires may slip (loss of traction) or vehicle may tip, resulting in possible operator injury or death. • Do not exceed 30% grade (17°) laterally. Vehicle becomes unstable as fluid levels are shifted. Internal components may not be properly lubricated causing vehicle damage. Tires may slip (loss of traction) or vehicle may tip, resulting in possible operator injury or death. • Travel on inclines, slopes, ramps and grades only as follows: — Loaded Forklift: with forks (and load) pointing uphill. — Empty Forklift: with forks pointing downhill. WARNING When the ATLAS is being operated without counterweight, care must be taken to avoid tipping the vehicle over. Boom extension must be kept at a minimum. Failure to comply could result in serious injury or death to personnel. WARNING Fuel is very flammable and can explode easily. To avoid serious injury or death: • Keep fuel away from open flame or any spark (ignition source). • Keep at least a B-C fire extinguisher within easy reach when working with fuel or on a fuel system. • Do not work on fuel system when engine is hot; fuel can be ignited by a hot engine. • Post signs that read “NO SMOKING WITHIN 50 FEET (15 m)” when working with open fuel, fuel lines or fuel tanks. WARNING Use extreme care when lifting counterweight with forklift. Counterweights weigh 5800 lbs (2633.2 kg) and its center of gravity (CG) is off center. Never allow forks to tip forward. Always tie counterweight lifting eyes to the lifting forklift. Counterweight must be handled using another 10K ATLAS/10K carriage and lifted through lifting eyes located at the top of the counterweight. Keep hands or fingers out of holes for counterweight pins. Failure to comply could result in serious injury or death to personnel. b TM 10-3930-673-10 WARNING CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU. Carbon monoxide is a colorless, odorless, DEADLY POISONOUS gas and, when breathed, deprives body of oxygen and causes SUFFOCATION. Breathing air with carbon monoxide produces symptoms of headache, dizziness, loss of muscular control, a sleepy feeling, and coma. Permanent BRAIN DAMAGE or DEATH can result from severe exposure. The following precautions MUST be followed to ensure personnel are safe whenever arctic heater or engine is operated for any purpose. Otherwise, injury to personnel may result. • DO NOT operate arctic heater or vehicle engine in enclosed area without adequate ventilation. • BE ALERT at all times during vehicle operation for exhaust symptoms. If symptoms are present, IMMEDIATELY EVACUATE AND VENTILATE the area. Treat affected personnel as follows: expose to fresh air; keep warm; DO NOT PERMIT PHYSICAL EXERCISE; if necessary, give artificial respiration as described in FM 4-25.11 and get medical attention. • BE AWARE; neither the gas particulate filter unit nor field protection mask for nuclear-biologicalchemical protection will protect you from carbon monoxide poisoning. THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD VENTILATION. WARNING • Dry cleaning solvent MIL-PRF-680 Type III is an environmentally compliant and low toxic material. However, it may be irritating to the eyes and skin. The use of protective gloves and goggles is suggested. Use in well-ventilated areas. Keep away from open flames and other sources of ignition. • NOTE: P-D-680 Type II is no longer in use and has been replaced by MIL-PRF-680 Type III. WARNING Personnel hearing can be PERMANENTLY DAMAGED if exposed to constant high noise levels of 85 dB (A) or greater. Wear approved hearing protection devices when operating or working within 61 ft (19 m) of vehicle when engine is running. Personnel exposed to high noise levels shall participate in a hearing conservation program in accordance with TB MED 501. Hearing loss occurs gradually but becomes permanent over time.

Section I. 1-7 1-8 1-9 1-11 1-12 1-13 1-14 GENERAL INFORMATION 1-1. SCOPE a. Type of Manual. This manual contains operation and operator maintenance instructions for the ATLAS. b. Equipment Name and Model Number. The ATLAS (All Terrain Lifter Army System) Forklift Truck, SKYTRAK 10000M, NSN 3930-01-417-2886, is equipped with a 6,000 lb and a 10,000 lb lifting carriage. The vehicle is manufactured by TRAK International, Inc. c. Purpose of Equipment. The ATLAS is designed for loading and unloading munitions and other palletized items from transport vehicles and containers. The ATLAS is also designed for use as a standard rough terrain forklift. d. Special Limitations on Equipment. The ATLAS has no special limitations. Normal limitations such as travel speed, lift capacity, etc., are discussed in Para 1-10. 1-1 TM 10-3930-673-10 1-2. MAINTENANCE FORMS AND RECORDS Department of the Army forms and procedures used for equipment maintenance will be those prescribed by DA Pam 738750, The Army Maintenance Management System (TAMMS). 1-3. CORROSION PREVENTION AND CONTROL (CPC) Corrosion Prevention and Control (CPC) of Army materials is a continuing concern. It is important that any corrosion problems with the forklift be reported so that the problem can be corrected and improvements can be made to prevent the problem in the future. While corrosion is typically associated with rusting of metals, corrosion can also include deterioration of other materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem. If a corrosion problem is identified, it can be reported using Standard Form 368, Product Quality Deficiency Report. Use of key words such as “corrosion, rust, deterioration, and cracking” will ensure that the information is identified as a CPC problem. 1-4. DESTRUCTION OF ARMY MATERIAL TO PREVENT ENEMY USE Command decision, according to the tactical situation, will determine when the destruction of the forklift will be accomplished. A destruction plan will be prepared by the using organization unless one has been prepared by a higher authority. For general destruction procedures for this equipment, refer to TM 750-244-6, Procedures for Destruction of Tank-Automotive Equipment to Prevent Enemy Use (US Army Tank-automotive and Armaments Command). 1-5.

GENERAL Your Preventive Maintenance Checks and Services table lists the inspections and care of your equipment required to keep it in good operating condition. 2-3. PMCS PROCEDURES a. The Item Number column of your PMCS is the source for the number used on the TM Number Column on DA Form 2404. b. The Interval column of your PMCS table tells you when to do a certain check or service. (1) Before you operate. Always keep in mind the CAUTIONS and WARNINGS. Perform your before (B) PMCS prior to the equipment leaving the containment area or performing its intended mission. (2) While you operate. Always keep in mind the CAUTIONS and WARNINGS. Perform your (D) PMCS when the equipment is being used in its intended mission. 2-16 TM 10-3930-673-10 (3) After you operate. Be sure you perform your after (A) PMCS after the equipment has been taken out of its mission mode or returned to the containment area. (4) Do your weekly (W) PMCS once a week. c. The Procedure column of your PMCS table tells you how to do the required checks and services. Carefully follow these instructions. If you do not have the tools, or if the procedure tells you to, have Unit Maintenance do the work. d. If your equipment does not perform as required, refer to the manual troubleshooting section for possible problems. Report any malfunctions or failures on the proper DA Form 5988-E or refer to DA Pamphlet 738-750. NOTE The terms ready/available and mission capable refer to the same status: Equipment is on hand and is able to perform its combat missions (AR 700-138). e. Equipment Is Not Ready/Available If column: This column tells you when and why your equipment cannot be used. f. Always do your PMCS in the same order so it gets to be a habit. Once you've had some practice, you'll spot anything wrong in a hurry. g. When you do your PMCS, take along a rag or two. h. While performing PMCS, observe CAUTIONS and WARNINGS preceding those operations which could endanger your safety or result in damage to the equipment. WARNING • Dry cleaning solvent MIL-PRF-680 Type III is an environmentally compliant and low toxic material. However, it may be irritating to the eyes and skin. The use of protective gloves and goggles is suggested. Use in well-ventilated areas. Keep away from open flames and other sources of ignition. • NOTE: P-D-680 Type II is no longer in use and has been replaced by MIL-PRF-680 Type III. (1) Keep it clean: dirt, grease, oil and debris only get in the way and may cover up a serious problem. Clean as you work and as needed. Use drycleaning solvent (P-D-680) to clean metal surfaces. Use soap and water when you clean rubber or plastic material. (2) Bolts, nuts and screws: Check that they are not loose, missing, bent or broken. You can't try them all with a tool, of course, but look for chipped paint, bare metal or rust around bolt heads. Tighten any bolt, nut or screw that you find loose. (3) Welds: Look for loose or chipped paint, rust or gaps where parts are welded together. If you find a bad weld, report it to Unit Maintenance. Change 1 2-17 TM 10-3930-673-10 2-3. PMCS PROCEDURES (CONT) (4) Electric wires and connectors: Look for cracked or broken insulation, bare wires and loose or broken connectors. Tighten loose connections and make sure the wires are in good condition. (5) Hoses and fluid lines: Look for wear, damage and leaks. Make sure clamps and fittings are tight. Wet spots show leaks, but a stain around a fitting or connector can also mean a leak. If leakage comes from a loose fitting or connector, tighten the fitting or connector. If something is broken or worn out, either correct it or report it to Unit Maintenance. (6) Vehicle must be on level ground in order to get correct fluid level measurement. i. It is necessary for you to know how fluid leaks affect the status of your equipment. The following are definitions of the types/classes of leakage you need to know to be able to determine the status of your equipment. Learn and be familiar with them and REMEMBER - when in doubt, notify your supervisor. CAUTION Equipment operation is allowable with minor leakages (Class I or II). Of course, consideration must be given to fluid capacity in the item/system being checked/inspected. When operating with Class I or II leaks, continue to check fluid levels as required on your PMCS. Class I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops. Class II Leakage of fluid great enough to form drops, but not enough to cause drops to drip from the item being checked/inspected. Class III Leakage of fluid great enough to form drops that fall from the item being checked/inspected. 2-4. LUBRICATION INSTRUCTIONS a. Refer to TM 10-3930-673-20-1. b.

STEERING THE FORKLIFT The forklift can be operated in three steering modes as selected with the steer select control switch: four wheel steer, two wheel steer, and crab steer. WARNING Do not turn fast. This may cause forklift to tip, lose the load, and possibly cause injury or death to personnel. This is particularly true in the four wheel steering mode. Turn vehicle in a lower gear or a slower speed. CAUTION • Before changing steering modes, synchronize steering (refer to Para 2-9, d. Steering System Synchronization.). Failure to follow this caution will result in vehicle mistracking and tire damage. • Forks extend beyond end of carriage. Be aware of swing of forks when turning. Allow for adequate clearance between forks and other objects. TR00039 a. Four Wheel Steering. Move the steer select control switch to the right position. Front wheels will steer in the direction that the steering wheel is turned; while the rear wheels will steer in the opposite direction. This mode allows an extremely short turn radius. It also enables the rear wheels to follow the tracking of the front wheels – an advantage in mud or sand conditions. 2-42 TM 10-3930-673-10 TR00040 b. Two Wheel Steering. Move the steer select control switch to the center position. Front wheels will steer in the direction that the steering wheel is turned; while the rear wheels will remain in the fixed forward position. This mode is used for on-highway travel or at higher speeds. TR00041 c. Crab Steering. Move the steer select control switch to the left position. All wheels will steer in the same direction. This mode permits the operator to move vehicle sideways toward the landing point of the load. This is especially helpful in tight quarters on the job, where there is not enough space to move a conventional forklift back and forth several times in order to line up at the exact spot in front of the loading location. d. Steering System Synchronization. Use the following procedures to align the front and rear wheels if wheels are not set in the same direction after you change steering modes (four wheel, two wheel, crab steer). (1) Use the steering wheel to put rear wheels in a straight ahead position. (2) Move the steer select control switch in the two wheel position (center). (3) Use the steering wheel to adjust front wheels to a straight ahead position. (4) Move the steer select control switch to desired mode for continued operation. 2-43 TM 10-3930-673-10 2-10.

HIGHWAY TRANSPORT a. General. (1) The ATLAS is highway transportable with a minimum of restrictions. However, because of its 100.2 inch width, the ATLAS exceeds the maximum legal limit of 96 inches for most state’s noninterstate highways. Permit requirements will vary depending upon local regulations and conditions, but in general the shipper must: (a) Submit DD Form 1266 to the installation transportation officer (ITO) 2 weeks before the planned movement. (b) Be aware that travel may be restricted to daylight hours on normal workdays. (c) Be prepared to use “wide load” signs, amber lights, and escorts. (d) Determine if blanket permits are available for specific prime movers, such as a heavy equipment transporter. (2) With maximum road speed of about 23 mph, the ATLAS can move over highways for short distances under its own power. With the powertrain disconnected, it can be towed (see Para 2-31.) (3) Refer to Appendix F for additional transportability information. b. Prime Mover Selection. (1) The physical size and weight of the ATLAS allow highway transport of the ATLAS by a variety of vehicles. In selecting a transporter, the proposed route and local availability of wide load permits must be considered. Table 1-2 presents a comparison of military semitrailers. Table 1-2.

INTRODUCTION F-1. GENERAL a. Purpose and Scope. This appendix is for transportation officers and other personnel responsible for safe transportation of the ATLAS. It provides data for planning and executing movement of the ATLAS worldwide. Included are physical characteristics of the ATLAS, safety precautions, technical data on transport modes, and lifting and tiedown procedures. The major dimensions and weights given in this manual are US customary and equivalent SI (metric) units. Approximate values appear in parentheses following the customary-unit value. Transport modes are presented in F-4. Modes of Transportation. b. Related Publications. Additional information on transport procedures can be found in: FM 55-65, Strategic Deployment by Surface Transportation. TB 9-2300-281-35, Standards for Overseas Shipment or Domestic Issue of Special Purpose Equipment. TM 38-250/AFR 71-4, Preparation of Hazardous Materials for Military Air Shipment. c. Definitions. Technical terms that may be helpful while using this appendix are: (1) Axle Limits. A load limit set by highway officials or designers of ship decks and aircraft as the maximum axle (or group of axles) weight that can be supported. (2) Center of Gravity (CG). The balance point of a suspended item. The ATLAS counterweight is used to shift CG to the rear. CG location is indicated by a symbol stencilled on the vehicle. (3) Curb Weight (CW). Total weight of operational ATLAS including fuel, all system fluids, and on-vehicle basic issue items (BII). CW does not include crew weight, which in this case is less than 1 percent of the gross vehicle weight. (4) Gross Vehicle Weight (GVW). CW plus payload. For transport purposes, a forklift has no payload. Therefore the GVW equals the CW. (5) Safe Working load (SWL). The SWL is the maximum recommended load that should be exerted on an item. SWL is also referred to as “working load,” “working load limit,” or “resultant safe working load.” Such rated load values are for inline pull. (6) Loading Restraint Factors (LRF). The LRF, given in this appendix for the surface and air modes, are considered to be the “G” factors that can be expected in military transport. F-1 TM 10-3930-673-10 F-2. SAFETY a. General. Even though the ATLAS has no special hazardous or dangerous characteristics during exposure to normal transportation environments, several general safety considerations and precautions are important. (1) Check the entire vehicle to be sure loose items are properly secured. (2) Have fire extinguishers readily available when operating the ATLAS. (3) Make sure only qualified personnel operate the ATLAS. (4) Never permit riders. This is a one-person machine. (5) Do not leave the ATLAS unattended while the engine is running. (6) Do not allow the ATLAS to exceed 3 miles per hour during loading and unloading operations. (7) Do not drive the ATLAS on public highways without the appropriate safety equipment. (8) Adhere to all local, state, federal, and host-nation safety laws and regulations applying to commercial carriers. b. Hazardous Material Considerations. The basic ATLAS does not contain hazardous material. Regulations or transportation procedures covered diesel-fuel-powered vehicles will apply. F-3. EQUIPMENT DESCRIPTION a. General. (1) The ATLAS is designed for loading and unloading munitions and other palletized items from transport vehicles and containers. The ATLAS is also designed for use as a standard rough terrain forklift. The ATLAS can handle boxes, palletized ammunition loads, and other palletized items from transport vehicles and containers. The vehicle frame can be tilted 9 degrees to left or right, which allows vehicle to be level when traversing a sideslope. The attachment can be raised to a nearly horizontal position for loading and unloading munitions. The forks tilt, level, and sideshift to maneuver loads. With 6K carriage, lifts loads of 6,000 lbs to a height of 28 ft. With 10K carriage, lifts loads of 4,000 lbs to a height of 27.5 ft, and 10,000 lbs to a height of 17 ft, and can tow other vehicles weighing 33,500 pounds or less. The operator can select one of three steering modes: two wheel, four wheel, and crab wheel. The ATLAS is all-weather operational, and can ford in up to 36 inches of water. The ATLAS has a maximum speed of 23 mph over level ground with evenly distributed load. F-2 TM 10-3930-673-10 b. Technical Data. The following selected characteristics and data apply to the ATLAS.

F-7. LOADING RESTRAINT FACTORS The loading restraint factors (LRF) used for surface and air modes are the “G” (acceleration of gravity) loading factors that can be expected in military transport. The tiedown arrangements shown in the figures are based on the following: -restraint factors are applied independently in each direction -restraint load (GVW times the LRF) was resolved into resultant lashing loads, allowing for tiedown angle -lashing loads are less safe than safe working load (SWL) of the restraint (that is, chain) Highway: The Transportation Engineering Agency highway LRFs are: -0.7 in the forward direction (relative to the transporter) -0.3 in the aft and vertical directions -0.1 in the lateral direction Rail: The Association of American Railroads recommended rail LRFs are: -3.0 in the longitudinal direction (relative to the railcar) -2.0 in the lateral and vertical directions F-13 TM 10-3930-673-10 F-7. LOADING RESTRAINT FACTORS (CONT) Marine: The Military Sealift Command (MSC) design LRFs are: -1.2 in the lateral direction (relative to the ship) -0.7 in the longitudinal direction -0.2 in the vertical direction MSC LRFs are for severe conditions Actual marine LRFs vary. Marine tiedown restraint depends on the size of the ship (decreasing on larger vessels), the expected sea state to be encountered, and the stow location of a given ship. Generally, the restraint required will increase for locations high and forward (or aft) in the ship. The most severe conditions will occur on exposed “weather decks,” where strong wind and wet conditions add to the problem. A ship’s crew may require additional lashing on exposed decks. Below-deck locations that are closer to the vessel’s center of gravity and rotation will experience less severe motion. Air: The USAF aircraft LRFs are: -3.0 in the forward direction (relative to the aircraft) -2.0 in the vertical direction -1.5 in the aft and lateral directions F-8. ESTIMATING TIEDOWNS The number of lashings required to safely tie down the ATLAS for highway transport on a typical truck/semitrailer can be estimated in the following manner: Step 1- Determine the amount of longitudinal restraint needed. (With this method, the required vertical and lateral restraint is covered by the longitudinal factors.) -The highway loading restraint factor (LRF) is 0.7 (from Para 6-6) in the forward direction: 33,500 (ATLAS GVW) x 0.7 = 23,450 pounds -The highway LRF is 0.3 in the aft direction: 33,500 x 0.3 = 10,050 pounds Step 2-Determine the amount of chains needed. -The angle to semitrailer deck and the angle to the angle to the side are assumed to be 45 degrees. (cos 45 x cos 45 = 0.5) -The SWL of the requisite 1/2-in. chain is 13,750: 23,450 = 3.4 (rounded up to 4) Number of forward loading chains = 13,750 x 0.5 Number of aft loading chains = 10,050 = 1.5 (rounded up to 2) 13,750 x 0.5 F-9.

Was brought to you by me: Liberated Manuals -- free army and government manuals Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends? I am setting this document FREE.
